Public or Private Sector Wage Leadership? An International Perspective*

Whether a government acts as a wage leader, placing pressure on private‐sector wages (more open to competition), or whether it plays a passive role and merely follows wage negotiations in the private sector, there are important implications for macroeconomic development, particularly in small open economies and/or countries that are members of a monetary union, such as those of the European Monetary Union. With the notable exception of the case of Sweden, opinion on this issue is still divided. In this paper, we look at public‐ and private‐sector wage interactions from an international perspective (18 OECD countries). We focus on the causal two‐way relationship between public and private wage setting, confirming that the private sector, on the whole, appears to have a stronger influence on the public sector, rather than vice versa. However, we also find evidence of feedback effects from public wage setting, which affect private‐sector wages in a number of countries. When the private sector takes the lead on wages, there are few feedback effects from the public sector, while public wage leadership is typically accompanied by private‐sector feedback effects.     

Drivers of customer likelihood to join grocery retail loyalty programs. An analysis of reward programs and loyalty cards

This paper aims to identify which personal features of customers may determine their likelihood to join a grocery retail loyalty program. We consider five aspects: price sensitivity, search for variety, shopping enjoyment, attitude toward loyalty schemes, and one personality trait: privacy concerns. Some of these variables have already been explored in the literature. Where our research breaks new ground is in establishing the difference between profiles of customers attracted by two of the most common types of loyalty programs currently used by grocery retail firms: a reward program and a loyalty card. The two kinds of program evidence differences in how they are managed, and we posit that the drivers of likelihood to take part in each are different. The study was carried out using logistic regression with a sample of 600 clients of a Spanish supermarket chain. Findings show that one particular type of customer is more likely to take part in these schemes: those displaying little shopping enjoyment, who are greatly concerned with privacy, and who show a favorable attitude toward loyalty programs in general. Furthermore, as expected, differences were observed between drivers of participation likelihood in reward programs and loyalty cards.     

A Note on Tests for Market Integration in a Multivariate Non‐Stationary Framework

In this note relationships among agricultural prices are studied to offer a guide to the degree of market integration. Unlike many previous studies, which examine market integration using pairs of prices, we conduct testing in a multivariate framework to exploit the information embodied in the indirect price linkages. We focus on the formulation of hypotheses that identify the cointegration space using time series data on European pork and lamb markets. Results indicate that the national markets for pork are more closely integrated than those for lamb. Extraneous market information is exploited in an attempt to identify the cause of this segmentation in the European lamb market, although results do not support any of the hypotheses proposed.     

Knowledge acquisition and corporate entrepreneurship: Insights from Spanish SMEs in the ICT sector

The contingent perspective on the corporate entrepreneurship–performance relationship has focused mainly on the influence of factors either environmental or internal to the organization. Only recently have researchers turned their attention to the relational context and specifically to inter-organizational alliances’ potential to influence this relationship. Our paper analyzes how knowledge acquisition from alliances affects the corporate entrepreneurship–performance relationship in a sample of Spanish SMEs from the Information and Communication Technology sector (ICT). The results obtained show that both corporate entrepreneurship and knowledge acquisition have a positive influence on performance but that the moderating effect of knowledge acquisition on the relationship between corporate entrepreneurship and performance is negative and it varies depending on the level of knowledge-based resources of the firm.     

Path dependence view of export behaviour: A relationship between static patterns and dynamic configurations

The main objective of this work is to understand the extent to which a relationship exists between static patterns and the dynamic configurations of a firm's export behaviour. The premise of our investigation is that the set of exporting decisions adopted over a period of time can be explained, in part, by the export pattern of the firm at the start of that period. Our empirical work is based on a sample of 754 exporting firms covering a 4-year period (2002–2006). Data were obtained from the Survey of Business Strategies (SBS). Our results support the path dependent focus of internationalisation, find some interdependences among three dimensions of export behaviour (extent, entry mode and scope), in static and dynamic fields, and support the idea that export experience influences some of the changes in foreign behaviour at one point in time, but not all. Our work contributes to the literature as it is one of the first works that (1) simultaneously analyses static and dynamic variables; (2) establishing relationships between both variables; (3) different dimensions of international export behaviour are introduced jointly; and (4) these relationships are contextualised according to the firm's export experience.     

The transmission mechanism in a changing world

The paper aims to identify those factors that cause changes in the speed and strength of the international transmission of output shocks from the USA to specified European economies. These factors are identified through the use of generalized impulse response functions conditioned on histories defined by an abrupt transition VAR. The chosen transition variables comprise changes in exchange rates, financial prices, international capital flows, trade links and monetary policy instruments. Besides the identification of asymmetric responses, the proposed model is useful in analyzing the strong effect of the recent US recession on the European economies and changes in business cycle synchronization over time.

Estimators for the common principal components model based on reweighting: influence functions and Monte Carlo study

The common principal components model for several groups of multivariate observations is a useful parsimonious model for the scatter structure which assumes equal principal axes but different variances along those axes for each group. Due to the lack of resistance of the classical maximum likelihood estimators for the parameters of this model, several robust estimators have been proposed in the literature: plug-in estimators and projection-pursuit (PP) type estimators. In this paper, we show that it is possible to improve the low efficiency of the projection-pursuit estimators by applying a reweighting step. More precisely, we consider plug-in estimators obtained by plugging a reweighted estimator of the scatter matrices into the maximum likelihood equations defining the principal axes. The weights considered penalize observations with large values of the influence measures defined by Boente et al. (2002). The new estimators are studied in terms of theoretical properties (influence functions and asymptotic variances) and are compared with other existing estimators in a simulation study.     

Workers or Employers: Who is Shaping Wage Inequality?

An extensive micro data set matching firms, establishments and their employees, is used to study the determinants of earnings inequality in Portugal and its evolution from 1983 to 1992, with the Theil index, its decomposition, and the decomposition of its change as tools of analysis. The relevance of both worker and employer attributes in shaping earnings inequality and its trend is quantified. The impact of the firm on wage inequality in a European country is compared to the situation in the USA, and the results suggest that a more regulated and centralized European bargaining system might reduce the scope for firm action. A profile of an economy undergoing modernization, where rising labour market inequality signalled the lack of an adequate labour force, can be drawn, with the minimum wage having nonetheless a certain narrowing effect on the earnings distribution.
